COUPLING.

1'?) all ar/n/m it ma concern:

Be it known that I, CURTIS l. hilctilruui, a citizen of the UnitedStates, residing at ihlil'tm, in the county of Summit and State of Ohio,have invented new and useful Improvements in Couplings. of which thetollowing is a specification.

This invention relates to an improved coupling device for unitinginstrun'lentalilies such for instance as a tractor and a drawn truck,the object thereof is to provide a simplr. durable coupling for thepurpose named, and cilicient in use to permit the coupling op orationand also permit the free swinging ol' the members coupled together withrespect to each other.

The invention more particularly resides in providing a coupling memberfor supporting the li'orward end of the reach or bar of the drawn trueltto facilitate the coupling and uncoupling operation.

With the foregoing and other objects in view, the invent on consists inthe novel eonstructiou, combination and arrangement of partsconstituting the invention to be hereina't'lor spccilically describedand illustrated in the accoulpanyiup drawings which form a part hereofwherein is shown the preferred embodinw'id ot' the invention. but it isto be understood that changes, variations and modifications can beresorted to which come within the scope of the matter hereinafterclaiiutal.

tn the drawings in which similar reference numerals indicate like partsin the dill'erent figures,

l ig'ure l. is a plan view of my improved coupling showing so much ofthe frame of a tractor as will illustrate the means for mounting thesame; and. Fig. 2, is a vertical section taltcn on line. X. of Fig.1. 1.

Referring to the drawings in detail, the rel'erence numerals 1 and 2denote the longitudinally cxtcnding side bars of a frame such as anautomobile tractor. Mounted onthe frame is the fixed member 3 of thecoupling held in place by hold-fast devices 4 and provided with anupwardly-extending huh 5 near its center, from which extend a pluralityof arms (3 "which rest upon the frame bars 1 and 2. In the upper face ofthe hub portion 5 of the, member 3 is a central reccss 7 surrounded byan upturned marginal annular ridge 8 constituting a horizontal bearingsurface for a purpose to be later described. The hub portion 5 isprovided Specification of Letters Patent.

with a central opening 9 in which is a kingholt 10. The movable elementof the coupling embodies a complementary member 11 consistingof anelongated trough-slmped body portion with :1 depending ordownwardlv-inelined rear end portion 19.. The forward end of thecoupling is provided with an u )wardlvrxtending standard the upperportion of which is provided with a horizontal opening 1 lspuced fromthe member 13 and provided with an aperture to receive a pin 15 thelower end of which is suitably ancliored in a recess in the lowerportion of the member. The under face of the member 11 is provided witha downwardly-tinned marginal annular ridge registering with the annularridge 8 and adapted to engage the same to permit free rota.- tion of themember 11 with respect to its companion member.

Along, the marginal portions of the members 11. are twoupwaidly-extending flanges 1,7 which form in connection with the fioorof the member 11 a seat for a purpose to be later described. and in thespace between the marginal flanges 17 is a countersunk opening toreceive the head of the king-bolt It That portion of the member 11between the side flanges is adapted to receive the forward end of areach, bar'or tongue 18 of the drawn vehicle and the forward end of thereach is provided with an aperture through which may be passed the pin15 for securely lockingthe end of the reach to the movable member ll yetpermitting the reach to swing horizontally under service conditions inunison with the horizontal revolution of the member 11 on the hub 5 as ahearing. The downwardly and rearwardly-inclincd por tion 12 constitutesa means for-sustaining and guiding the end of the reach immediatelypreceding the coupling operation so that by placing the end of the reach0n the inclined portion 12 and backingdhe tractor or drawing forwardlythe drawn truck the end of the reach will slide along the floor (if themember 11 until the aperture therein is in registration with the openingin the head 14 of the standard 13, after which the pin 15 may beinserted for completing" the coupling, operation.

When it is desired to perform the uncoupling operation, a reversal ofthe foregoing operation is followed out.

a king-bolt, a movable coupling member mounted ongjthe upper bearing;face of said hub, said movable coupling member pro-f 'vided with aforwardly bositioneui-send upwardly extending standenl having a headoverhanging the lower portion to provide a recess to receive theendnfthe reach {or bar,

and a F 1 reach, or detachably coupling sal .in'embers together.
